Im looking for ideas because I’m considering growing mushrooms again. I grew 
a couple of batches of oyster mushrooms, some of the easiest to grow. Problem 
is I’m renting so don’t feel like digging a walapini. But, yes, always 
looking for stacked functions.

Hi Jeremy,

that sounds interesting.
And how about growing mushrooms in a combined walipini-root cellar when 
heated by the sun in summer?
Multifunctional!
:-)
